Question

Which is true about the interaction between the upper respiratory system and respiration? The lower respiratory tract brings air to the upper respiratory tract so that gas exchange can occur in the nose. The upper respiratory tract brings air to the lower respiratory tract so that gas exchange can occur in the lungs. The upper respiratory tract does not play a role in respiration. All respiration occurs in the upper respiratory tract

Answer 1

As we inhale, our upper respiratory tract (nose, mouth, nasal cavity, larynx and pharynx) delivers oxygen to our lower respiratory tract (lungs). As the air enters our lungs, there would be an air exchange. Oxygen is absorbed in the alveoli and carbon dioxide is expelled outside the body.

 

Answer 2

Answer:

The upper respiratory tract brings air to the lower respiratory tract so that gas exchange can occur in the lungs.

Explanation:

The respiratory system is formed by pathways or tracts, as they are also called, lower and upper respiratory, and the first is formed by those organs that are located outside the rib cage, which are the external nose, nasal cavity, pharynx, larynx, beyond the upper part of the trachea. The lower respiratory tract, in turn, refers to those organs that are located in the thoracic cavity, which are the lower part of the trachea, the bronchi, bronchioles, alveoli, and lungs, as well as the pleural layers and the muscles that form the thoracic cavity.

The upper respiratory tract is responsible for air entering the body. It is through it that air is directed to the lower tract so that gas exchange occurs within the lungs.
